MEXICO CITY, Mexico (APF) — The World Cup kicks off Thursday with co-hosts Mexico taking on South Africa in the Estadio Azteca in Mexico City, launching a sprawling tournament of 48 teams that will last nearly six weeks. The extravaganza hosted by the United States, Mexico and Canada is the biggest World Cup in history, stretching until the final in New Jersey on July 19. It is projected to generate a record-breaking $13 billion in total revenue.
